I am in the high arctic less than a thousand miles from Earth's north pole in a location chosen for its resemblance to the planet Mars. Here, I, and my small team, will transmit a series of webcasts aimed at children participating in summer activities sponsored by the Mars Institute, Challenger Center for Space Science Education, and The Explorers Club. On the way up to Devon Island I had a chance to fiddle with my latest gadget - er, I mean tool: a new iPhone. One of the things I put on it was a film I saw in high school called "Silent Running".
